MarMac Sealing Tape is a high-strength, single-sided tape comprised of a rubberized bitumen with a continuous filament thermoplastic fiber for reinforcement. The fiber adds tensile strength and provides resistance to tear. The tape is supplied in 60′ rolls and utilizes both kraft paper and film-release sheets which are removed prior to application. Provides a fast, non-volatile method for sealing seams and adhering similar/dissimilar composites/structures. Used to transition existing asphalt surfaces to new asphalt. Aggressively bonds to steel, HDPE, concrete and asphalt. The sealing tape’s reinforced mastic membrane is used for road joint and crack repair as well as piezoelectric traffic counter installation. The sealing tape is a specially formulated rubberized mastic with a peel-able protective release film, backed with a high strength, heat resistant woven polypropylene fabric.

Made in the USA.
